Well the reason I ask is because the goblins have kind of programmed themselves to have as-low innate magic as possible. Gives them some advantages, and then one BIG advantage, but also means that they simply keel over and die if they can't siphon life out of other magical things. So if you throw a goblin into a concrete jail with no one else around, he'll just expire. (This is also why they're only familiars for powerful wizards with connections to other planes)So, if sand doesn't have the ability to provide this magic to make them live, then I'd have to throw them somewhere with more life, for instance, a jungle.

Where he'll meet only the kindliest and gentlest people and certainly not a band of crazy inbred forest rapists or snake men (I don't know why but I always imagine that jungles are filled with snake men)
